Product Review: ABB TB82PH

Have you already chosen your pH transmitter? Wait, we have more options for you! At the end of the month you can analyze all of them and decide which will work best for your new application.

The crew from ABB has appeared on Visaya before and joins us today with the TB82PH, a loop-powered multi-parameter transmitter. Let’s check out the features and see how this device can add value to your application.

Grab a gazpacho, take a seat, have a read, and draw your conclusions!

Whatcha got there?

Okay, when I saw the TB82PH for the first time, the thought occurred to me that it needed a design upgrade – badly. It looks so old-fashioned that I wouldn’t blame you if you thought it came from the 80s. We’ll see in a bit if the features come from the 21st century.

The simple display shows the principal process variable and an alert if the device has a problem. It’s fairly compact, 144 x 144 x 171 millimeters, according to the datasheet. It weighs 1.9 kilograms without the pipe mounting hardware, and adding that hardware bumps it to 3.4 kilograms.

The “multi-parameter” bit means that it can connect different sensors to the transmitter, which should make it pretty flexible, right? Actually, the transmitter has only one channel, and you need to choose your measurement before you buy, so it’s not that flexible after all.

What can it do?

You can use the TB82PH to measure pH, oxidation reduction potential (ORP), and selected ions (pION) quite easily. The ABB reps claim that your device can withstand the harshest environments, and with an enclosure rated at IP65, they’re pretty close to the mark. And it comes with approvals to cover the common options – Factory Mutual (FM), Canadian Standards Association (CSA), and ATREX 100A.

Now, another important feature is seamless integration. Today, we expect vendors to guarantee transparent connections between field devices and control systems. The TB82PH has analog, which you can integrate anywhere, but it’s not transparent. It also has HART, FOUNDATION Fieldbus, and PROFIBUS PA.

You know I’m an enthusiast of digital communication, so I’m disappointed in the lack of options like Ethernet protocols and wireless.

Why should I care?

Because ABB has a well-earned reputation in the automation market. Yes, the TB82PH is a simple device, but that doesn’t mean it’s not good. It sticks to the basics to give you a smooth user experience, reliable process values, and basic diagnostics.

If you want fancy features, ABB has them, just not here. Same goes for the sensors. But if you need a straightforward device to measure your process, you got it in the TB82PH, and it probably won’t pinch too much from your wallet, either.

Conclusion

If you want a simple device for an application without many requirements, you need to check this out. Otherwise, you may want to browse through the rest of ABB’s portfolio.
